Extensions can be declared within the scope of another message. If this is an extension field, then this will be the scope it was declared in nil if was declared at a global scope.
var extensionScope: Descriptor? { get }s26SwiftProtobufPluginLibrary15FieldDescriptorC14extensionScopeAA0F0CSgvp What are these?399QBimport SwiftProtobufPluginLibraryA reusable framework for building protoc plugins in Swift.
final class FieldDescriptorDescribes a single field of a message. To get the descriptor for a given field, first get the Descriptor for the message in which it is defined, then find the field. To get a FieldDescriptor for an extension, get the Descriptor or FileDescriptor for its containing scope, find the extension.
final class DescriptorDescribes a type of protocol message, or a particular group within a message. Descriptors are not directly created, instead they are constructed/fetched via the DescriptorSet or they are directly accessed via a messageType property on FieldDescriptors, etc.
var containingOneof: OneofDescriptor? { get }The oneof this field is a member of.
var containingType: Descriptor! { get }The Descriptor of the message which this is a field of. For extensions, this is the extended type.
let defaultValue: String?The explicitly declared default value for this field.
var enumType: EnumDescriptor! { get }When this is a enum field, that enum’s EnumDescriptor.
let features: Google_Protobuf_FeatureSetvar file: FileDescriptor! { get }File in which this field was defined.
var fullName: String { get }Fully-qualified name of the field.
var hasPresence: Bool { get }Returns true if this field tracks presence, ie. does the field distinguish between “unset” and “present with default value.” This includes required, optional, and oneof fields. It excludes maps, repeated fields, and singular proto3 fields without “optional”.
let index: IntIndex of this field within the message’s fields, or the file or extension scope’s extensions.
var internal_isGroupLike: Bool { get }Helper to see if this is “group-like”. Edition 2024 will likely provide a new feature to better deal with this. See upsteam protobuf for more details on the problem.
let isExtension: BoolIf this is an extension field.
var isMap: Bool { get }True if this field is a map.
var isOptional: Bool { get }Shorthand for label == .optional
var isPackable: Bool { get }Is this field packable.
var isPacked: Bool { get }If this field is packable and packed.
var isRepeated: Bool { get }Shorthand for label == .repeated
var isRequired: Bool { get }Shorthand for label == .required.
let jsonName: String?JSON name of this field.
let label: Google_Protobuf_FieldDescriptorProto.Labeloptional/required/repeated
var messageType: Descriptor! { get }When this is a message/group field, that message’s Descriptor.
let name: StringName of this field within the message.
let number: Int32The field number.
let oneofIndex: Int32?The index in a oneof this field is in.
var options: Google_Protobuf_FieldOptionsThe FieldOptions for this field.
var realContainingOneof: OneofDescriptor? { get }The non synthetic oneof this field is a member of.
var requiresUTF8Validation: Bool { get }Returns true if this is a string field and should do UTF-8 validation.
var type: Google_Protobuf_FieldDescriptorProto.TypeEnum { get }Declared type of this field.
func deprecationComment(commentPrefix: String) -> String func getLocationPath(path: inout IndexPath) var explicitDefaultValue: String? { get }The explicitly declared default value for this field.
var hasOptionalKeyword: Bool { get }var oneof: OneofDescriptor? { get }The oneof this field is a member of.
var proto: Google_Protobuf_FieldDescriptorProto { get }var realOneof: OneofDescriptor? { get }The non synthetic oneof this field is a member of.
